EGW Picatinny Scope Mount Features The EGW Picatinny Scope Mount bolts directly to the factory scope mount holes on the Browning BBR receiver so no drilling or tapping is required during installation. Precision machined from extruded 6061-T6 aluminum the rail is cut with full-width cross slots gauged to MIL-STD 1913 specifications within plus or minus 0.002 inches ensuring rings seat consistently and securely. This slot-and-rail spacing allows for fast simple adjustment of eye relief and gives the shooter far more flexibility in scope and ring selection than a proprietary factory base. The mount accepts both true Picatinny and Weaver-style scope rings broadening compatibility with rings already on hand. A milled center channel reduces the mount s overall weight without sacrificing rigidity keeping the rifle s balance close to stock. The kit includes socket head Torx screws and a wrench and EGW recommends roughly 20 in-lbs of torque along with a drop of blue Loctite on the screws for a mount that stays put under recoil. Finished in black to match factory receiver finishes the base gives the Browning BBR a clean factory-look upgrade path to modern optics. This is a straightforward way for BBR owners to move away from older mounting systems and toward widely available Picatinny-compatible rings.
